I need to know how to disable the ABS system on my 2002 Durango SLT.

It's 4-wheel drive with what I think they call "all-wall" rear ABS.

Meaning that only the rear breaks are antilock, but the fronts lock-up.
This makes the vehicle very dangerous to drive under emergency condition.

Please let me know, and thanks.

pull the fuse.
lots of discussion on this in durango section at dodgetalkDOTcom.
your front wheels aren't locking, it's the abs system dumping the fluid back to the resevoir to stop the skidding front wheels hence the truck lurches foward due to no brakes. Wonderful feeling isn't it? Make sure your tires have lots of tread and your pads/rotors are in good condition.
